Cast Iron Mining Jaw Crusher Spare Parts

The Stone crusher is widely used in mining, building materials, chemical industry, metallurgy and so on. The Stone Crusher is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa.

Advantage

1. Simple structure.

2.easy maintenance.

3. High crushing ratio.

4. even output granularity.

Working Principle

The strip and strip pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the movable jaw runs down, then the materials are crushed into pieces. It will become bigger when the movable jaw runs up. The movable jaw board leaves the fixed jaw board under the action of pole and spring , then the end products come out from the crushing cavity.

1. After starting crusher in operation, once the crusher makes an unusual percussion sound, we should stop moving forward ,identifying and eliminating defects , restart.

2. Crusher must be no-load to start. When the crusher is operating normally and then open to the mining equipments .We should add the ore mine to equipment gradually until full up .

3. Crusher should be given mine well-proportioned, ore can’t packed with crushing cavity ; to the maximum size don’t allow to exceed mine to the mine mouth width of 0.85 times; the same time when the crusher gives mine ,we should avoid the mine ore iron and the iron abundance of non- crushing material into crusher; Once we find non-crushing material through the port of discharge ,we shall immediately notify the belt transport staffs take measures in time, so as not to causing serious equipment accidents when mine will go into the next crusher.
